In my Velocity the strakes gravity feed to the sump. About a foot of 3/8" Al / rubber fuel line on each side, downhill all the way. I can run one tank plumb dry and have only a gallon or two gone out of the other. Like when there's a slight leak in a fuel cap or something.
If they're significantly uneven, you WILL get air if you select "Both" ... Jim S.

I don’t think so: connect two tanks (one full with water and one empty) to gravity feed Into Y connection. Than suck on the end and try to breathe. Let me know how it works :)
